What is telemarketing?
They are cold calls that try to sell you something.
How to opt-out
Use the National Do Not Call Registry, a Federal Trade Commission managed national list of phone numbers that telemarketers are not supposed to call. Home and cell numbers may be put on list, but not work phones, unless you work from home using your home phone number. Anyone you have done business with in the last 18 months is still permitted to call you. If you make an inquiry of a merchant, the merchant can call you for six months. Charities and politicians are allowed to call. For more information: http://www.ftc.gov/donotcall
